The purpose of this study was to examine the outcome of the patients operated on for malignant and borderline malignant ovarian tumors to search prognostic factors.<BR>A total of 26 patients who underwent surgery for malignant and borderline malignant ovarian tumors in our hospital between April 1993 to September 2000 were enrolled for this study. Medical records of the patients were reviewed.<BR>Of 26 patients, 24 patients had primary tumors. The outcomes of the patients withprimary tumors were analyzed. The average age of the patients was 60.0 years (range, 30-81). The most frequent cell type was serous tumor. After initial cytoreductive surgery, macroscopic lesions were present in 10 of the 24 patients. There were six postoperative deaths. In the 10 patients in whom tumor removal was incomplete at the firstoperation, two patients underwent a complete operation after chemotherapy. In the eight patients, macroscopic tumors remained. An estimated 5-year survival rate was 100% in stage II, 53.7% in stage III and 0% in stage IV. The patients in stages from IIto IV having the complete operation in the first or second surgery were all alive. However, the 3-year survival rate of those patients having the incomplete operation was25.0%.<BR>Our findings suggested that an increment of the rate of complete operation leads to longer survival.
